Mleczek et al. 2015 - Arsenic uptake in cultivated mushrooms from controlled substrates

Mleczek and colleagues tested how arsenic species in cultivation substrate affect arsenic accumulation in mushroom biomass. This is not a natural retail-occurrence survey, but it is a routeable experimental food-matrix source because it reports final mushroom arsenic concentrations under controlled substrate treatments. Total arsenic ranged from 1.97 +/- 0.14 mg/kg dry weight in Agaricus bisporus to about 68 mg/kg dry weight in Pleurotus strains under higher exposure conditions.

Key numbers

All concentrations are dry weight unless the paper states otherwise.

• The abstract reports the lowest total As in Agaricus bisporus at 1.97 +/- 0.14 mg/kg.
• The highest total As values reported in the abstract were Pleurotus ostreatus HK35 at 68.8 +/- 19.0 mg/kg and Pleurotus eryngii at 68.0 +/- 31.0 mg/kg.
• Agaricus bisporus biomass ranged from 341.24 +/- 13.16 g to 378.49 +/- 14.57 g across the substrate treatments described in the abstract.
• The experimental design distinguishes As(III), As(V), and dimethylarsinic acid substrate additions; the source therefore supports arsenic-species context but not a natural market distribution.

Methods (brief)

Mushrooms were cultivated on substrates amended with different arsenic species and concentrations. The authors measured arsenic in the final mushroom biomass and compared species/strain accumulation. The source is best treated as experimental substrate-transfer evidence, not a geographic market sample.

Implications

This source supports arsenic-total context for cultivated mushrooms and helps explain why low-As substrate controls matter. It should not be admitted to a clean retail mushroom benchmark without an explicit experimental-source flag, because substrate spiking can produce concentrations far above ordinary market levels. It is still useful for mechanism, worst-case sensitivity, and cultivation-risk pages.

Verification notes

• DOI, title, authors, journal, and year were taken from the PDF header.
• The source reports arsenic species in the substrate treatments, but the food-matrix concentration values summarized here are total arsenic in mushroom biomass unless the paper states otherwise.
• This page should remain flagged in routing as experimental-substrate evidence, not a routine retail occurrence survey.
